T0 ALLPERSONS TO WHOM THESE PRESENTS SHALL COME: 4 c

Be it known that 1,'H1RAM CnAMnnnLAIN, of Calais, in the count-y of Washington, and State of Maine,

have invented a new and useful Machine for Slicing and Mincing or Chopping Meat,ior other matters; and I;

do hereby declare the same to be fnlly'deserihed in the'following specification,` andV represented in the accompanying drawings, oi' which- Figure 1 is atop view,

Figures 2 and 3 ure vertical and transverse sections, and

Figure 4 an elevation of it.

In such drawings Adenotes the frame of the machine. A driving-shaft, B, suitably supported in bearings, upheld by the said frame, and provided with a crank, a, carries a spur-gear, b, which engages with a pinion, c, fixed on another shaft, d. The said shaft d is arranged over the driving-shaft, has a bell-crank, e, and carriesi a slicing-wheel or disk, f. This whccl is shown in `side view in Figure 5, and in section in Figure 6. It has'` three or any other suitable number of Athroats y fj g extending through it, there being a cutting-knife, z, likea" plane-iron fixed in cach of the throats, and so as to stand at an acute angle with the face or side of thcwheelQ Besides these knives, the wheel has a series of cutters or crosscut knives, itz', projecting from its face, `and in 4advance of cach knife la. The knives are to pass-down through the meat, preparatory to cach slice` being taken therefrom by each ot' the slicing-knives 7i h 71. Thus itwill be seen that by the conjoint operations of the` slicingand cross-eut knives slices will be cut from the meat, and such meat will be so eut into that each of the,

slices will be separated into several parts, all of which will pass through the throats of' the wheel and into the wheel-case C. The said case C surrounds the wheel and extends down to and opens through a platform, D,

arranged over the rotary mincing-tub E. A hopper, F, formed as shown in vertical section in Figure 47, andin` front view as exhibited in Figure 8, is so applied to the frame A and. the case C as to discharge into thesaid` case, and against the face of the wheel therein, an`y meat placed in such hopper. An adjustable shoe, c,`is` applied to the lower part of thc hopper, and held thereto by a screw, I, and a nut, m, the screw passing through. a slot in the inclined side or chute 'n of the hopper. The shoe is provided with lips o o which project upward from its edges and against thc opposite sides of the hopper. The purpose of the shoe is` to support` the meat.`

while it may be inl the act of being cut by the knives of the wheel, and such shoes adjustable in order that it` may be moved up as nearly to them as possible, and especially in Vany case of wearing or cutting away of its lower edge. The case C I construct in two separate parts, that is to say it is divided into two sectionspp byl a plane going through it transversely and through'the axis of the cutting-wheel; the same being to enable each` partp to be readily removed from the wheel for the purpose of'bcing cleansed, as occasion may require. Thesef parts are supported by small studs q qprojecting from them and resting ou' a crossfrail, r,"of the frame A, against which the said case C abuts, it being kept up to the rail by an arched bar, s, whose cndsare inserted in mortises or sockets t t made in the frame A. The mincing-tub E simply rests on the'upper side ofa horizontal worm-gear, t, a pivot, t2, from which extends into a hole, u', in a slide, u, placed betwecniand against two` parallel and dove-tailcd guides v e fixed on'tllc hase 'zu of the frame A. By means of the slide u and its guides n c the tub may be withdrawn from the wheel-case, or arranged in place underneath it, as circumstances may require, whether for discharging the minced meat from the tub, or for cleansing the said tub.' Small studsfar project horizontally from the periphery of the mincing-tub. Other studs extend vertically from 4the 'upper surface of the gear t. Each of the studs'nf, by contact with one of the studs 'j, causes the tub to revolve with the gear, when thc latter is in revolution. A worm or screw, 2, fixed on a shaft, G, engages with thetethof the worm-gear t. An endless belt, I-I, running on a pulley, I, fixed on the driving-shaft, and'ano'tlier pulley,

K, fixed on the shaft G, serve to transmit rotary'motion tothe said shaft G, when the driving-shnft is in the act ot' being revolved by manual power applied to its crank.

The meat, after havingbeen sliced and reduced in manner as stated, will bc discharged into the mincingtub. A knife, t', (arranged Vso as to play up and down within the said tub, and so moved by means of thcbell p crank e, a connecting-rod, K', and a pitman or shank, L, arranged as-representcd,) will mince or chop the meat while the tub may be in revolution.

In such machine I claim the following, that is to say- I claim the combination as well s the arrangement of the slicing,- and mincing or choppingmechanisms, lbstantially'as specified, the slicing mechanism consisting of the rotary wheel with its slicing and cross-cut nives, the, hopper and the whee1-case,-and the means of revolving the wheel, and the mincing mechanim, )nsisting of the rotary mincing-tub, its reciprocating knife, and mechanism -for operating the two, as speciied.

I also claim the combination of the adjustainle shoe K, with the hop-pier and the slicing-Wheel provided with 1e slicing and cross-cut knives, es described. i v

I also claim the combination and arrangement of the studs g q, and the rctziincr or arched hair `s with the 'ame A, and the slicing-whee1 case C, made in two parts and applied to the siicingqvheei, as specified.

I also claim the combination and arrangement of the slider u and itS guides v 11' with' the mincingmeehanm, when connected with e siicinglmechanism, and so as to operate therewith, as set forth.
